Abstract
A heat-transfer label including a non-wax, non-silicone release layer for use in decorating an article without leaving a visually discernible release residue on the decorated article. In a preferred embodiment, the label includes a transfer portion comprising a protective lacquer layer, an ink design layer over the protective lacquer layer, and a heat-activatable adhesive layer over the ink design and protective lacquer layers, the adhesive layer extending beyond the peripheries of the ink design and protective lacquer layers. The label also includes a support portion, the transfer portion being positioned over the support portion for transfer of the transfer portion from the support portion to an article upon the application of heat to the support portion while the transfer portion is placed in contact with the article. The support portion includes a carrier, the carrier preferably being a polyester film. The support portion also includes a non-wax, non-silicone release layer positioned over the carrier and in direct contact with the protective lacquer layer and the periphery of the adhesive layer.
